The best gaming KVM switch 2025: Why the TESmart DKS202-M24 stands out

In 2025, a truly high-quality gaming experience will no longer simply mean owning a powerful GPU or a monitor with a high refresh rate. The real bottleneck often lies within the signaling chain itself. – from the graphics card to the display, and especially in the intermediate devices that connect everything.

For gamers and creative professionals running multi-PC setups, the KVM switch has become a critical component. A poorly designed KVM can imperceptibly affect the frame rate, disable Adaptive Sync, or cause constant resolution resetting. This is precisely where the TESmart DKS202-M24 as one of the most powerful gaming KVM switches available in 2025.

1. What defines the ultimate gaming experience?

High-frequency displays are indispensable today.
Modern gaming monitors focus on much more than just resolution. Key features include:

  • High refresh rates (144 Hz, 240 Hz and more)

  • Variable Refresh Rate (VRR)-technologies such as G-SYNC and FreeSync

  • HDR-Support for higher contrast and realism

  • Low response times to minimize ghosting and motion blur.

Of these, the high refresh rate is the most immediately noticeable improvement – ​​especially in FPS, racing and competitive e-sports titles, where motion blur and reaction speed directly affect performance.


GPUs need to deliver more than just raw power.

Even the most powerful graphics card cannot reach its full potential if the output chain is unstable. High-end GPUs depend on the following:

  • Support for DisplayPort 1.4/2.1 or HDMI 2.1

  • Stable bandwidth for high resolutions and high refresh rates

  • Precise negotiation of display capabilities


The responsiveness of the keyboard and mouse is crucial.


At 240 Hz and above, input latency becomes more noticeable. Competitive gamers demand:
• High sampling rates (1000 Hz or higher)
• Reliable detection of USB devices
• No delays or reconnections when switching between systems


The overlooked factor: The KVM switch


In multi-PC gaming and workstation setups, the KVM switch needs to do more than simply "pass through" signals. A high-performance KVM switch must:
• Receive the full video bandwidth
• Preserve VRR, HDR and frame rate integrity
• Prevent black screens and resolution resets
• Ensure seamless switching between keyboard and mouse
Many common problems in multi-monitor gaming setups do not originate in GPUs or displays – but in inadequate EDID processing within the KVM.


2.What is EDID and why is it important?

EDID: The digital identity of the display

EDID (Extended Display Identification Data) is a standard defined by VESA that allows a display to communicate its capabilities to a source device. EDID contains information such as:
  • Supported resolutions and refresh rates
  • HDR and color depth capabilities
  • Timing and synchronization parameters
The graphics card relies entirely on the EDID to determine how to output video.

What goes wrong without EDID emulation?

For conventional KVM switches without EDID emulation:
  • The active video connection is physically disconnected during the switching process.
  • The source device recognizes the display as "remote".
  • The operating system rereads the EDID upon reconnection.
  • The display settings are reset (often to 60 Hz).

For gaming with a high refresh rate, this can mean the loss of VRR, disabled HDR, rearranged windows, or even black screens.


3. What EDID emulation can really do (and what it can't)

EDID emulation is not just caching.

A true EDID emulator continuously maintains a stable display identity for the source device – even if the physical display is temporarily disconnected.

In practice, EDID emulation means:

  • Storage and reproduction of the display's EDID data

  • Continuous provision of this EDID to the connected system

  • Preventing the system from detecting a screen separation

  • Elimination of renegotiation delays and display resets

The result:

  • Frame rates remain unchanged

  • HDR and VRR remain enabled

  • No black screens when switching.

  • Display arrangements remain intact

For gaming and professional graphics workloads, EDID emulation is a core stability feature, not an optional convenience addition.


4. Gaming with high refresh rates: DisplayPort vs. HDMI

Why DisplayPort remains the preferred choiceWhile HDMI 2.1 offers impressive bandwidth, DisplayPort remains the leading interface for high refresh rate PC gaming:DisplayPort advantages:

  • Mature ecosystem for high refresh rates

  • Strong VRR and Adaptive-Sync compatibility

  • Widely supported by 240Hz and e-sports monitors

  • Better suited for PC-centric gaming setups

HDMI 2.1:

  • Excellent for TVs and consoles

  • Increasingly powerful, but less common in high-end PC e-sports displays

For competitive PC gaming, DisplayPort remains the most reliable option.
